3 Claims.

This invention relates to new and useful improvements in the construction of buttonholes in garments. 1

v A main object of the invention is to provide a simple, economically constructed buttonhole structure for a garment which will permit the button to be inserted and removed with ease and with a minimum of Wear and tear on either thed thread connecting the button to the garment or on the buttonhole structure itself.

Further and more specic objects, features and advantages will more clearly appear from a consideration of the detailed specification hereinu after set forth, especially when taken in connection with the accompanying drawings which illustrate a present preferred form which the invention may assume and which form part of the specification.

In brief and general terms, the invention includes at least two layers of material one of which is provided with an angular buttonhole, the two layers being joined together along one side only of said hole.

' Preferably the hole is triangular and the layers are joined together along one side thereof above the base of the opening.

- More particularly, the construction permits the button to be slipped down between the two layers at the base of the opening and then slipped to one side between said layers. When the button is to be removed, since the layers at the opposite side of the opening are sewed or joined together, the button will ride over these joined edges and emerge with its upper half above the base line of the opening whereupon it can be moved vertically from the hole entirely with practically no wear and tear on the hole or on the threads connecting the button to the garment.

More particularly, the corner ofthe hole toward which the button is moved, when inserted,

provided with a depressed pocket to more firmly locate the button therein.

The present preferred form which the invention may assume is illustrated in the drawings, of which- Fig. 1 is a rear elevation, with portions broken away, of a part of a garment showing a series of buttonholes of my improved form;

Fig. 2 is an enlarged partial rear elevation of one buttonhole;

Fig. 3 is a horizontal cross section taken on the line 3-3 of Fig. 2;

Fig. 4 is a horizontal cross section taken on the line 4-4 of Fig. 1;

Fig. 5 is a cross section taken on the line 5 5 of Fig. l; and

Fig. 6 is a vertical crosssection taken on the line 6-5 of Fig. 2. l

Referring now to the specific form of the invention shown in the drawings, which is only. one form which the invention may assume, it is to be seen that the-area of the garment where are located the. buttonholes is formed of two main layers of material I and II constituting the respective front Iand rear layers thereof. Disposed between these layers IIJ and II (see Figs.` 1 `and 3) and reading from layer Il to layer ID area stiffening layer I2, a reinforcing layer I3, and a .layer I4 forming the rear .Wall or backing .layer of thebuttonhole opening.

The shape of the hole out in the layers II, I2 and I3 is angular and preferably somewhat triangular with an elongated base portion I5, a curved sloping left side I6, and a sharply sloped substantially straight right side I'I (as viewed in Fig. 2). As seen in the drawings, the layers II, I2, I3, and I4 are sewed together along the length of the left side I6 as seen in Fig. 3, but along the base I5 and the right side I'I only the layers II, I2, and I3 are sewed together. The button, shown in dotted lines in Fig. 1 has a semi-diameter just short of the height of the apex of the buttonhole opening. It is apparent that the button, on introduction, may be moved down between the two layers II and I4 along the base side I5 and then may be moved to the right to dispose its axis in the right corner of the angular opening, since the two layers II .and I4 along the right side II are not connected. In removing the button it is merely necessary to move it to the left, whereupon, since the two layers II and I4 are connected along the left side I6, the leftedge of the button will ride up over these joined edges and its upper half will emerge into view, after which it can be moved vertically to remove its lower half from between the layers I I and I4 below the base edge I5. It is of course to be noted that in reality we need only the two layers II and I4 to achieve the effect of the invention, since the layers I2 and I3 are merely introduced to make a more durable and finished product. It is also to be noticed that the right hand corner of the buttonhole slopes downwardly to form a sort of depressed pocket I 8 into which the threads connecting the button to the other side of the gariranent may lie when the button is in inserted posiion.

As Shown in Fig. 5, the button is sewed to a layer of cloth I9 forming the other side of the front of the garment. The layer l0 is the front of the garment on the buttonhole side. It will be seen that this construction will permit of the easy and rapid insertion and removal of the button with a minimum of wear and tear on the buttonhole and on the threads connecting the button to the garment. The layers of material I2, I3, and I4 are shown as extending integrally all along the garment back of the series of buttonholes, although it is to be noted that they may, if desired, be only used in the area immediately around the buttonholes.

While the invention has been described in detail and shown with respect to the accompanying drawing, it is not to vbe limited to such details, since many changes and modifications may be made in the invention Without departing from the spirit and scope thereof. Hence, it is desired to cover any and all forms and modications of the invention which may come withi in the language and scope of any one or more of the appended claims.

What I claim as my invention is:

1. A garment construction which includes four layers of material, three adjacent layers having formed therein aligned angular buttonholes, the four layers being joined together along one side of said angular opening, the three adjacent layers being joined together along the other sides of the angular opening.

2. A garment construction which includes four layers of material, successively a main layer, a stiffening layer, a reinforcing layer, and a backing layer, the rst three `layers being formed with aligned buttonholes of triangular shape, the fourth layer extending across said holes. the

lll

rst three layers being joined together around two sides of said holes, and the four layers being joined together around the third side of said holes.

3. A garment construction which includes four layers of material, successively a main layer, a stiffening layer, a reinforcing layer, and a backing layer, the rst three layers being formed with aligned triangular buttonholes therein, the base of said holes being iiat, one s ide above the base being curved and the other side above the base being sharply sloped downward in a substantially straight line, the junction of the base and the latter side joined to form a slightly depressed button-thread receiving pocket, the fourth layer extending across said holes, the first three layers being joined together around the base and straight side of the holes, and the four layers being joined together around the curved side of the holes.
